BRACELET-GAGE.

Specicaton of Letters Patent.

Patented May 11, 1920.

Application filed November 30, 1917. Serial No. 204,560.

To @ZZ whom t may concern Be it known that I, CHARLES H. Kmrrnn, a citizen of the United States, residing at Calrland, in the county of Alameda and State of California, have invented certain new and useful mprovements in Bracelet- Gages, of which the following is a specification.

This invention is a device by means of which a human wrist may be measured to determine the proper size of a bracelet or other similar article to be worn thereon.

The object of the invention is to provide a simple device which may be readily slipped over the wrist and adjusted to the size thereof, whereby bracelets and other similar jewelry may be accurately measured to fit the arm or wrist for which they are designed.

The invention will be hereinafter fully set forth and particularlyT pointed out in the claim.

In the accompanying drawing Figure 1 shows a perspective view of the device. Fig. 2 is an enlarged side elevation of the locking means in an open position. Fig. 3 is a viewv of same in a locked position, and Fig. 4: is a sectional view of Fig. 3 in a locked position.

Referring to the drawing 10 designates a band of resilient metal, sufliciently flexible to be bent around so that its ends 11 and 12 may overlap as shown. The end 12 is provided with a guide 13 through which the end 11 has been passed, said guide serving to retain the end 12 in position. The end 11 is provided with a guide 14C, having loop portions 15, through which the end 12 has been passed, said guide being provided with a longitudinal slot 16, registering with a similar slot in the end 11, and working in said slots is the cam portion 17 of a locking,- lever 18, pivoted to the guide 14;, as indicated at 19. The end 11 is preferably pointed and the body of the bend 10 is provided with a scale 20.

In operation, when it is desired to measure a wrist, the lever 18 is turned so as to lift the cam portion 17 out of engagement with the body of the band, whereby the ends will be free to slide, and the band may be opened wide enough to permit the passage of the hand. The band 10 is then closed until it is reduced to the desired size whereupon the lever 1S is returned so as to force the cam 1T against the body 10, pressing the latter against the loops 15, thereby locking the ends from further relative movement. The desired size of the bracelet is indicated on the scale 20 by the end 11.

Having thus explained the nature of the invention, and described an operative manner of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or allof the forms of its use, the following is claimed A measuring device of the character described comprising a band having overlapping ends, a guide member attached to one of said ends and having loop-like guide portions and a top plate and a cam lever pivoted to said top plate, the top plate and contiguous portion of the end to which said guide is attached having registering slots to receive said cam lever.

In testimony whereof I ailiX my signature.

CHARLES H. KEMPER.
